Giovanni Fonio vs Zdenek Kolar

Highlights

• • Kolar's career win rate and recent Biella form favor him on clay
• • Market requires >62.5% to break even; our model estimates 64%

Pros

• + Positive expected value at the current widely-available price (1.60)
• + Stronger recent form at the venue and on surface

Cons

• - Both players have relatively limited long-term samples at Challenger level, increasing uncertainty

Details

We compare the market price (Kolar 1.60 implied win probability 62.5%) to our estimate of Kolar's true win chance. Kolar presents stronger evidence of form and experience on clay: a higher career win rate (63-30 vs Fonio's 43-28), recent positive results at Biella, and more matches overall. Fonio's recent results show back-to-back losses in Genoa on clay, which lowers his immediate projection. Given those factors we estimate Kolar's true probability at 64.0%, higher than the market-implied 62.5%, producing positive expected value at the quoted 1.60 price.

Key factors

• • Kolar's superior career win-loss record and higher sample of matches
• • Kolar's recent positive results at this Biella event and on clay
• • Fonio's recent losses on clay (Genoa) indicating weaker immediate form
